BEST MODE FOR EMBODYING THE INVENTION

The examples according to the invention shall be described hereinafter with reference to the appended drawings.

EXAMPLES

FIG. 1 is a graphical view of the reality generating device according to the invention. According to this example, the reality generating device 2 is applied to the radio controlled motor toy car and a system block is as shown FIG. 1. A reality generating device 2 is comprised of a control transmitter 4 and a running body or radio controlled motor toy car 6 having an antenna and provides a superregenerating reception unit 8 for receiving the radio controlled signal, a control circuit unit 10 for decoding the received signal and a steering drive amplifying unit 12 and a power drive amplifying unit 14 for driving the steering drive unit 18 and the power drive unit 20 respectively in accordance with an output of the control circuit 10. The running toy is provided with a pseudo sound generating device 15 including a power switch SW 13, a power drive amplifying unit 14 and a speaker 22. In the pseudo sound generating device 15 is arranged a sound circuit unit or a microcomputer 16 into which each output signal which copes with the running mode of the decoder circuit and an actuation signal of the power switch is input as an input signal and a sound which copes with the input signal selected from the engine sound previously programmed to cope with the running mode and the effective sound other than the engine sound is output from the speaker through the amplifying circuit and with the engine sound the oscillation signal is generated to perform a driving actuation through the power motor drive circuit.

The superregenerating reception unit 8 arranged in the radio controlled motor toy car 6 receives a signal transmitted from the control remitter 4 and the received radio controlled is converted into a signal for controlling the steering drive unit 18 and the power drive unit 20 respectively at the control unit 10 connected to the superregenerating reception unit 8 and then transmitted to the steering drive amplifying unit 12 and the power drive amplifying unit 14 and the same signal drives the units 18 and 20. Thus, the radio controlled motor toy car 6 conducts the advancing and backing actuations as well as the left and right turning actuations in accordance with the actuation sticks (not shown) arranged in the control transmitter 4. When a power switch 13 of the radio controlled motor toy car 6 is put on the radio controlled signal from an output terminal of the control circuit 10 is received by the sound circuit 16 as an input signal and generates from the speaker the pseudo sound which copes with various actuation modes of the radio controlled motor toy car and the controlled oscillation signal is output to the power drive unit 20 by means of the power drive amplifying unit 14 connected to the sound circuit unit 16 which generates the pseudo sound and the oscillation according to the program stored in ROM not shown.

Generation system of the pseudo sound shall be described hereinafter in detail with reference to the appended drawings of FIG. 2 to FIG. 4B which are the flow chart Figures illustrative of the generation processes of various pseudo sounds and the oscillations by the sound circuit 16 in accordance with the running modes of the motor toy car operated under the radio controlled actuation and the radio controlled motor car toy shown in FIG. 5 as an example is a racing car.

FIG. 2 is a flow chart of the actuation of the reality generating device according to the invention in which the generation systems of the pseudo sound and the oscillation exercised in the sound circuit 16 are as follows. Namely, when the main power switch of the racing car is put on, then the sound circuit unit 16 regenerates the starter sound. Then, the starter sound data previously memoried in ROM are read out for composite tone which is in turn transmitted to a speaker 22 for generation of the starter sound(T2). This starter sound is a rotary sound of the cell motor of the real motor car when started and memoried previously in ROM. Subsequently, into the sound circuit 16 is input a start on signal of the idling signal for generating the idling sound(T4). The idling sound is generated from the speaker through the amplifying circuit arranged in the sound circuit unit 16. Simultaneously, the sound circuit 16 generates the oscillation which is read out from ROM.

FIG. 4A is a wave form diagram of the oscillation signal of the exemplified reality generating device according to the invention. This oscillation signal wave form intends to vibrate the voltage±A volt per the time t1=100˜150 ms. When the oscillation wave form is applied to two terminals provided the power driving unit, the tires are driven at the rotary angle of ±0.5 per the time t1=100˜150 ms. The sound circuit unit 16 when no signal is received the control circuit unit 10 transmits the signal per 100˜150 ms to the power driving oscillation 14 which drives the power driving unit 20 at the same timing so that the tires make a weak oscillation(T6). After measurement of a particular time, for example an approximate time of from 2˜4 sec. by means of a timer program arranged in the sound circuit unit 16. After measurement taken place the sound circuit 16 regenerates an engine racing roar sound(T). The sound circuit unit 16 reads out engine racing roar sound from ROM and synthesizes the sound for transmission the speaker 22 in order to regenerate the engine facing roar sound.

The sound circuit 16 also regenerates an oscillation and reads out the oscillation data from ROM. FIG. 4B is a wave form diagram of the oscillation signal of the reality generating device of another example according to the invention. The wave form of the oscillation signal of FIG. 4B is for vibrating the voltage±A volt per the time t2=60˜90 ms. The frequency is preferably shorter than the wave form shown in FIG. 4A(t1>t2). When the wave form is applied to two terminals provided in the power driving unit, tires are driven at the rotary angle±0.5 per the time t1=60˜90 ms.

The sound circuit 16 after the idling sound is generated transmits the signal per 60˜90 the power driving amplifier unit 14 which drives the power driving unit 20 a the same timing for generating a weak oscillation of the tires(t10). The short oscillation frequency represents an increment of the rotation of the engine on account of an elevation of the oscillation frequency.

When a turbo key of the transmitter is put on, the step is shifted to B1 of FIG. 3A which is a flow chart of the turbo key of another example of the reality generating device according to the invention.

When the turbo key is selected for the on state in the reality generating device, the high speed driving signal is transmitted to the power driving amplifier unit 14 through the superregenerating reception unit 8 and the control circuit unit, so that a weak oscillation due to the reality generating device is discontinued (3A2) to start the high speed driving. Simultaneously, the turbo key on signal is transmitted through the superregenerating reception unit 8, while the idling sound or the engine racing roar sound is discontinued to read out the high speed sound data from ROM and the high speed sound data; is regenerated(3A6).

Then, the reality generating device is left in waiting the left and right keys actuation (3A8). When the left and right keys are no in actuation, the high speed driving and regeneration of the high speed sound data are continued to wait the turbo key return (3A14), whereas when the left and right keys are operated, the left and right steerings take place by means of the steering drive unit 18 through the superregenerating reception unit 8 and the control circuit unit 10 and simultaneously the signal is transmitted to the sound circuit unit 16 through the control circuit 10 and the skid sound data are read out from ROM to regenerate the skidding sound from the speaker (3A12) for subsequent waiting of the turbo key(3A14).

When the turbo return is not input even in waiting, the left and right keys actuation is again left in waiting(3A8). On the other hand, when the turbo key return is input the high speed drive signal is transmitted to the power drive amplifier 14 for reduction of the speed through superregenerating reception unit 8 and the control unit 10 of the reality generating device. Simultaneously, the signal is transmitted to the sound circuit 16 through the control circuit 10 and the skidding sound data are read out from ROM to regenerate the skidding sound from the speaker 22(3A16) for subsequent return to A1 of FIG. 2.

When the turbo key of the transmitter is put off while the forward key is put on, the step is shifted to B2 of FIG. 3B which is a flow chart of the forward key of an example of the reality generating device according to the invention.

When the forward key is put on, an intermediate signal is transmitted to the power drive amplifier unit 14 through the superregenerating reception unit 8 and the control circuit unit 10 to discontinue a weak oscillation(3A2) so that the intermediate drive signal of the power drive amplifying unit 14 is started(3A4). Simultaneously, the forward key on signal is transmitted to the sound circuit unit 16 through the superregenerating, while the idling sound or the engine racing roar are discontinued to read out the high speed data from ROM and to regenerate the high speed sound data from the speaker 22(3A6).

Then, the left and right keys actuation is left on waiting(3A8). When the left and right keys are not operated, regenerations of the high speed driving and the high speed sound data are continued for waiting the turbo key return(3A14). When the left and right keys are on actuation, the left and right steering takes place(3A10) by means of the steering drive unit 18 through the superregenerating reception 8 and the control circuit 10 and simultaneously the signal is transmitted to the sound circuit 16 through the control circuit 10 and the skidding sound data are read out from ROM for regeneration of the skidding sound data from the speaker 22(3A12) for subsequent waiting step of the turbo key return(3A14).

In the waiting position of the turbo key return, when the turbo key return is not input, the left and right keys actuation is again left in the waiting position(3A8). When the turbo key return is input, however, the high speed drive signal is transmitted to the power drive amplifying unit 14 through the regeneration reception unit 8 and the control circuit 10 of the reality generating device. Simultaneously, the signal is transmitted to the sound circuit unit 16 through the control circuit 10 and the brake sound data read out from ROM for regeneration of the brake sound data from the speaker 22(3A16) for subsequent A1 step of FIG. 2.

When the turbo key is put off in the transmitter while the forward key is put on, the actuation is shifted to B2 of the FIG. 3B which is a flow chart of the forward key of the reality generating device.

When the forward key is put on, the intermediate speed drive signal is transmitted to the power drive amplifier 14 through the superregenerating reception unit 8 and the control circuit unit 10 so that the weak oscillation is discontinued(3B2) for starting the intermediate speed drive of the power drive amplifier unit 14(3B4). Simultaneously, the forward key on signal is transmitted to the sound circuit unit 16 through the superregeneration reception unit 8 to discontinue the idling sound or the engine racing roar and the intermediate sound data is read out from ROM for regeneration of the intermediate speed sound data from the speaker 22(3B6).

The left and right keys actuation stands by(3B8). When the key actuation is discontinued the generations of the intermediate speed drive and the intermediate sound data are continued for waiting the forward key return(3B14). When the left and right keys actuation takes place, the left and right keys actuation performs the left and right steering by the steering drive unit 18 through the superregeneration reception unit 8 and the control circuit unit 10 and simultaneously the signal is transmitted to the sound circuit unit 16 through the control circuit unit 10 to read out the skid sound data from ROM for regeneration of the skid sound data from the speaker 22(3B12) and then the forward key stands by(3B14).

When the forward key return is not input during the forward key stands by for return, the reality generating device again stands by for the left and right keys actuation (3B8).

When the forward key return is input the signal is transmitted to the power drive amplifying unit 14 for reduction of the high speed drive through the superregeneration reception unit 8 and the control circuit unit 10. Simultaneously, the signal is transmitted to the sound circuit unit 16 for reduction of the high speed drive through the control circuit unit 10 to read out the brake sound data from ROM for regeneration of the brake sound data from the speaker 22(3B16) and subsequent return to A1 step of FIG. 2.

When the turbo key of the transmitter is put off while the back key is put on, the step is shifted to B3 of FIG. 3C which is a flow chart of the back key of the exemplified reality generating device according to the invention.

When the back key is put on, the back key drive signal is transmitted to the power drive amplifying unit 14 through the superregeneration reception unit 8 and the control circuit 10 to discontinue the weak oscillation(3C2) while the back drive is started(3C4). Simultaneously, the back key on signal is transmitted to the sound circuit unit 16 through the superregeneration reception unit 8 to discontinue the idling sound or the engine racing roar so that the low speed sound data is read out from ROM for regeneration of the low speed sound from the speaker 22(3C6).

The left and right keys stand by actuation (3C8). When the left and right keys are not on actuation, the generations of the back drive and the low speed sound are continued to stand by the back key(3C14). When the left and right keys are on actuation, the left right steering takes place by the steering drive unit 18(3C10) through the superregeneration reception unit 8 and the control circuit 10. Simultaneously, the signal is transmitted to the sound circuit unit 16 through the control circuit 10 to read out the skid sound data from ROM for regeneration of the skid data from the speaker 22(3C12). Thereafter, the back key stands by for return(3C14).

In FIG. 2, when the back key is not selected the main switch 13 for power source of the racing car stands by for actuation (T20). In case, the power source switch 13 is selected, the step A1 discontinues again the idling sound(T22) and also the oscillation (T24).

As shown FIG. 1, the reality generating device according to the invention may provide the sound circuit 16 for receiving an actuation processing signal from the control circuit 10, the power on-off switch 13, the power drive amplifying unit 14 and the speaker 22 for conveniently obtaining a compact device and variations of the pseudo sound generation control and the oscillation control may be carried by merely changing the program energized by the sound circuit unit 16 arranged in ROM and various pseudo sounds and oscillations may be realized according to the situations and environments.

The realities of examples according to the invention may further be enhanced as shown FIGS. 5 and 9. FIG. 5 is a perspective view of the radio controlled racing car toy providing the reality generating device according to the invention in which the radio controlled toy car 6 comprises the body 30 and the chassis providing a tire 32 a and a tire 32 b together with head lights 36 a and 36 b. Further, the control circuit 10 is connected to a lamp or LED arranged in the head lights 36 a and 36 b for lighting in association with starting of the turbo key and the forward key so that the reality is considerably enhanced.

A method of generating the reality as claimed in claim 9, wherein the actuation sound previously determined to cope with the actuation state and the effective sound other than the actuation sound are output through the speaker to generate the engine sounds of the high speed sound, the intermediate sound, the low sound, the engine racing roar, the idle racing sound or the idling sound selectively and further to generate the braking sound, the curve skidding sound and horns.
 11. A reality generating program which generates the actuation sound of the toy upon actuation, the oscillation for realizing the actuation of the running toy drive unit and the actuation sound and the oscillation simultaneously when desired.
 12. A reality generating program as claimed in claim 11, wherein the actuation sound previously determined to cope with the actuation state and the effective sound other than the actuation sound are output through the speaker through the amplifying circuit for generating the engine sounds of the high speed sound, the intermediate speed sound, the low speed sound, the engine racing roar, the idle racing sound or the idling sound selectively and further to generate the braking sound, the curve skidding sound and horns.
